                   [Hewlett-Packard Bulletin HPSBUX0209-221]

October 9, 2002 17:00 GMT                                         Number N-006
PROBLEM:       The NativeLdapClient portion of LDAP-UX Client Services in the
               LDAP-UX Integration package provides native access to a
               directory server, bypassing NIS. The pam_authz module in this
               portion allows the system administrator to use netgroups or
               authenticate to various services. Vulnerabilities with this
               pam_authz module have been identified in versions B.02.00 and
               B.03.00 which can allow r-commands or other services to execute
               under the wrong user id.
AFFECTED       LDAP-UX B.02.00 and B.03.00
PLATFORM:      HP9000 Series 700/800 running HP-UX releases 11.00 and 11.11.
DAMAGE:        Attackers could gain unauthorized privileges.
SOLUTION:      Update to HP LDAP-UX Integration version B.03.01.
VULNERABILITY  The risk is HIGH. An attacker could potentially gain
ASSESSMENT:    unauthorized access, elevate privileges to root level, and run
               arbitrary code of his/her choice.
